Patented Sept. 27, 1932 UNiTEDsTATE-s PATENT ori-*ica` THOMAS E. KANE,OF MANSFIELD, MASSACHUSETTS,ASS`IGNOR TO 'JJIEX'IJILIEF Y FINISH-INGMACHINERY COMPANY, A CORPORATION'OF RHODE ISLAND CALENDERING MACHINElThis invention relates to a calendering machine, and has for its objectto provide a machine for -inisliing a sheet of paper, or the like, by asinglev pass thru the machine,

@to accomplish the resultof two passes .thru

the machine which have been previously required. i

A further obj ect of the invention is to provide means whereby the workmay be subjected at different points during its passage thru the`machine to different amounts of pressures by the calendering rolls.

A still further object of the invention is the provision of aconstruction by which twov 15g-different pressures may be used in themachine with one pressure supplementing the; other pressure iii actingon a certain group of rolls of the machine thru which the work passes. Yv 2a; With these and other objects in view, the invention consistsof-certain novel features of construction, as will be more fullydescribed, and particularly pointed out in the appended claims. Y 25;;In the accompanying drawings:

Fig. 1 is an end elevation ofthe calendering machine. i

Fig. 2is afront elevation ofthe same. Fig 3 is a section on line 3-3 ofFig 1. Fig. 4 is a section on line 4 4 of Fig. 1. Fig. 5 is adiagrammatic view of the manner of applying pressure to the differentrolls of the machine; and Y Fig 6 is a similar diagrammatic Viewillusjtrating a modified construction in which pressure is applied inopposite directions rather Y than in the same direction,as shown in Fig.5.

In the use of calendering machines, particularly for finishing paper,and the like, it has heretofore been found desirable to run the workthru the machine with the pressure upon the rolls relatively light andthereafter running the paper again thru the machine with a greateramount of pressure upon the rolls, thus necessitating the handling andreeling of the paper between passes; and in order that this handling andreeling of the work may be avoided, I have provided a Inachine in whichthe paper is first subjected il!) to a light pass and thereafter in thesame 12, and pressure may be applied to this slide machine and withoutreeling subj'ectedto a ,heavier pressurethus eliminating one han--provided with a vertical opening 11, the marginal edges 12 of which aremachined to provide the sliding surface of a guideway for the rollbearings 13 which are located in the spaced pair of support standards,and in which rolls-14 are mounted andextend 'from one bearing totheotherand in contact with each other, as illustrated in Figs. 1l and 2.

These rolls are arranged in groups, the lower group or series of rollsmay consist of any desired number, that which I have chosen for thepurposes of illustration herein being eight, one in contact with andresting upon the other in the machine, as illustrated inFigs. 1 and 2.y. y v,

The bearing 15 of the uppermost roll of this group or series, is securedto a slide member 16 slidably mounted in 'theguideways 11,

Veo.Y

member 16 thru the lever 17 pivoted at 18 on the standard and connectedto the slide member 16 at 19 in any suitable manner. Y A link y2Oconnects the lever 17 to the hydraulic pressure device 21 of a knowntype, describedV more specifically inrPatent No. 1,587,784, dated June8, 1926, the pressure being conn trolled vby a hand wheel 22. v Y Theslide member 16 is of a generally: rectangular construction` and isprovided with an opening 23, the marginal edges 24 of which are providedwith'v a inished'surface for thesliding engagement ,of` the roll,bearings 25, in which bearings there are mounted rolls `26eXtendingfromv onestand-V ard to the other. These rolls 26 are in contact witheach other andthelowermostroll l of this upper groupvor seriesis in-contact with the uppermost roll 15jof the first or lower` group orseries of rollsmentioned to v which pressure is applied thru the abovesaid mechanisms.

The rolls 26, however, which have their bearings slidably mounted in theframe 25,

-" are not affected by the pressure which acts thru the frame 16. Aseparate pressure is applied to the uppermost roll, and acts thru guiderods 27 which are secured to the uppermost roll 28 of the second orupper group or seriesthru the shaft 29 upon which pressure is applied bymeans of lever 30 pivoted as at 31 and drawn downwardly thru the link 32by a hydraulic pressure-applying device 33 of the type heretoforementioned and which is controlled by a hand wheel 34.

The pressure is applied thru a hydraulic device 33 which acts upon theroll 28 and in turn upon the rolls below the same in the member 16 andis thus transmitted to the roll 15 of the lower group, which alsoreceives pressure thru the sliding frame and thus the two separatepressures which act upon the two groups are added together so that theircombined force acts upon the rolls 15 and the rolls below to apply agreater pressure 'to the work as it passes therethru than when passingthru the upper series of rolls, the bearings of which are mounted intheslide member 16.

I have found this manner of applying pressure preferable, but asimilarresult may also be obtained which I have illustrated in F 6. in whichthe bearing for the middle roll 35 is fixedly mounted in the supportstandards and opposite pressures indicated by the arrows- 36, 37 Vareapplied to the upper and lower series of rolls which may accomplish thesame result but a greater pressure, of course, will be necessary at thearrow 3T on the lowergroup of rolls than where two A pressures are addedtogether to have their combined forces effective as in the diagrammaticshowing of Fig. 5, similar to that in Fig. 1 heretofore pointed out.

Bearings which'are slidably mounted are illustrated at 38, and areprovided with afiXed side lip 39 and removable side lip 40 to engage themarginal guide surfaces 12 to smoothly direct their vertical movement.

The foregoing description is directed solely towards the constructionillustrated, but I desire it to be understood that I reserve theVprivilege of resorting to all the mechanical changes to which the deviceis susceptible, the invention being defined and limited only by theterms of the appended claims'.

I claim:

1. In a calendering machine, a series of slidably mounted rolls, meansfor applyingpressure thereon, a second series of rolls slidably mountedin a portion of the means thru which said pressure is applied to thefirst series, and means for applying pressure to said second series ofrolls. f

2. In a calendering'machine, a series of slidably mounted contactingrolls, a slidably mounted frame thru which pressure is applied to theuppermost roll of said series, and a series of contacting rolls slidablymounted on said frame and in contact with the uppermost roll of thefirst said series.

3. In a calendering machine, a series of slidably mounted contactingrolls, a slidably mounted frame, means for applying pressure thru saidframe to the uppermost roll of said series, and a series of contactingrolls slidably mounted in said frame and in contact with the uppermostroll of the first said series, and means for applying pressure on theuppermost roll of the second said series.

4. In a calendering machine, a frame coinprising a pair of spacedupright support standards having gudeways therein, pairs of bearingsslidable in said guideways at the lower portion thereof, rolls mountedin and extending between said pairs of bearings and.

resting with their surfaces one on the other, a pair of slide membersslidably mounted in said guideways in the upper portion thereof andattached to theupper pair of said'slidably mounted bearings, guidewaysin said slide members, a pluralityrof pairs of bearings slidably mountedin the guideways in said slide members, rolls mounted in and extendingbetween said pair of bearings, means for applying pressure to theVuppermost pair of bearings in said slide member for transmission to therolls therebeneath, and separate and independent means for applyingpressure to said slide member to transmit pressure to the bearingsl towhich it is connected and to the rolls therebeneath, whereby the rollsin said slide member are unaffected by the last mentioned pressure.

5. In a calendering machine, a plurality of series of slidably mountedrolls, one of said series of rolls being capable of slidingindependently of the other series, and independent pressure means foracting separately and independently on said series of rolls in the samedirection,

6. In a calendering machine, a plurality of series of slidablyl mountedrolls, one of said series of rolls being capable of slidingindependently of the other series, and pressure means for actingseparately on one of said series of rolls and jointly on the other ofsaid seriesof rolls in the same direction.

In testimony whereof I aiiiX my signature.
